Specification of Letters Patent.

Patented July 25, 1905.

Original application filed December 6, 1902, Serial No. 134,201. Divided and this application filed May 22, 1903. $erial No. 158,259.

To all whom it may concern.-

Be it known that I, RUDOLF KRON, a citizen of the Republic of Switzerland, and a resident of Golzern, Kingdom of Saxony, German Empire, have invented new and useful Improvements in the Process of the Manufacture of Yarn from Short-Fiber Material, of which the following is a specification.

This invention, whlch constitutes part of the subject-matter of my application for United States Patent, Serial No. 134,201, filed December 6, 1902, of which the present application is a division, has for its object a process for the manufacture of yarns from short-fiber material, as paper-pulp, asbestos, cellulose, and the like, such manufacture being effected in such a manner that an endless web of suitable width is formed from the short-fiber material in the paper-machine, that such web is divided in separate small strips, and the so-divided small strips are rolled in a moist condition on a common core or mandrel. The magazine-roll thus resulting is hereafter supplied to a s inning, spooling, or twisting machine, an the separate strips are drawn ofi from the magazine-roll and spun directly in a moist condition to arn. y In the known processes paper in a dry condition is either divided into strips and wound up to rolls or wound up in the entire web. While drawing off this web from the roll it is cut into strips which are twisted together and spun to yarn, or the paper-pulp web being still in a moist condition is divided on the paper-machine into separate strips which are twisted together in their moist condition. The twine so produced is spun in a moist condition on the spinning or twisting machine, as described, for instance, in the German printed specifications Nos. 73,601 and 79,272.

However, the present invention has for its object to produce or manufacture from the web, being in a moist condition and divided into strips, a solid and compact magazineroll which canbe piled in a moist condition for many months and is suitable to form a new and important article of manufacture and industry. The separate strips are drawn off in a moist condition from this magazine-roll and spun directly to yarn. One strip can be drawn off separately and spun separately to one-thread yarn, or two, three, four, or more strips can be drawn off at 'a time and spun simultaneously for the manufacture of more thread-yarn. The

rolled up in a still moist condition on a com mon core or mandrel of wood, board, paper, and the like in the form of a'solid compact roll. For the purpose of drawing off again the strips from this magazine-roll and of spinning them directly to yarn the magazineroll is supplied either as a whole to the spinning, spooling, or twisting machine or subdivided into sections of suitable width by cutting the magazine-roll through by means of knives, saws, or other mechanical means, inclusively the core or mandrel, such roll forming a whole by the common core. In this manner a number of small rolls are produced containing two, three, four, or more strips rolled up side by side.

The drawing off of the magazine-roll is effected either from the outer layer against the center in a continuous manner or from the center against the periphery of the roll. In thelatter case the core or mandrel out through is removed from the separate sections of the roll after cutting of the magazine-roll, so that the core of the roll is a hollow one. The beginning ends of the strips are drawn off from the opening formed and the strips wound off from the interior of the roll.

In the drawings annexed to the above description, Figure 1 shows a web formed of small strips divided and rolled up at a time in a moist condition to a magazine-roll. Fig. 2 shows in view, partly in section, a section of a magazine-roll containing part of the core or mandrel common to all strips. The strips to be spun or twisted are drawn off at the outer surface or periphery of the roll. Fig. 3 shows also in view, partly in section, another section of the magazine-roll from which the core or mandrel is removed, and the strips are drawn off from the interior opening of such roll. Figs. 4 and 5 show in longitudinal view and transverse section part of a spinning machine in which the small strips drawn ofi from the magazine-roll formed by such stri s placed side by side are spun to yarn in t e well-known manner.

a is the web, composed of small separate strips formed by dividing such web in a moist condition on a paper-machine. These strips are rolled up to a magazine-roll I), placed round a core or mandrel 0. Such a broad magazine-roll may be subdivided into secand e a beam for the guiding-eyes e.

tions, the cutting-knife cutting through the core or mandrel of wood or other material, as shown in Fig. 3. This core can remain within the section of the magazine-roll when the strip or strips is or are drawn off from the periphery, whereas if such strips are drawn off from the interior of the magazine-roll, as shown in Fig. 4, the core or mandrel is removed from the magazine-roll. The magazine-rolls or sections of such magazine-rolls are supplied to a spinning, spooling, or twisting machine, as seen from Figs, 4 and 5, in which (1 is a support for the magazine-rolls b The strips drawn oil from the magazine-rolls are passed through these eyes and around a circular beam from which the strips are led to the fliers g and bobbins h. These bobbins and fliers are the same as those in general use and being of well-known construction it is not necessary to describe or illustrate them in detail.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The process described of manufacturing from short-fiber material in a moist condition magazine-rolls composed of separate strips, such process consisting in forming a continuous web from a mass of said material, dividing said web at intervals in its width in the direction of its length to form strips and rolling up the so-formed strips in the moist condition on a core into the form of a solid compact roll from which such strips may be drawn off separately to be supplied in the moist condition to a spinning, spooling or twisting machine. 7

2. 'As a new article of manufacture, a magazine-roll of short-fiber material and in a moist condition, consisting of an endless or continuous web formed of the pulp of short-fiber material in a moist condition divided in its longitudinal direction at suitable distances apart and wound around a core, which magazine-roll may be subdivided into sections from which the strips lying side by side can be drawn off in a moist condition separately.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 4th day of May, 1903.
